+/* THIS IS NOT AN X CONSORTIUM STANDARD */

+/*
+ * Big fonts suffer from the following: All clients that have opened a
+ * font can access the complete glyph metrics array (the XFontStruct member
+ * `per_char') directly, without going through a macro. Moreover these
+ * glyph metrics are ink metrics, i.e. are not redundant even for a
+ * fixed-width font. For a Unicode font, the size of this array is 768 KB.
+ *
+ * Problems: 1. It eats a lot of memory in each client. 2. All this glyph
+ * metrics data is piped through the socket when the font is opened.
+ *
+ * This extension addresses these two problems for local clients, by using
+ * shared memory. It also addresses the second problem for non-local clients,
+ * by compressing the data before transmit by a factor of nearly 6.
+ *
+ * If you use this extension, your OS ought to nicely support shared memory.
+ * This means: Shared memory should be swappable to the swap, and the limits
+ * should be high enough (SHMMNI at least 64, SHMMAX at least 768 KB,
+ * SHMALL at least 48 MB). It is a plus if your OS allows shmat() calls
+ * on segments that have already been marked "removed", because it permits
+ * these segments to be cleaned up by the OS if the X server is killed with
+ * signal SIGKILL.
+ *
+ * This extension is transparently exploited by Xlib (functions XQueryFont,
+ * XLoadQueryFont).

+** File:
+**
+** xvmain.c --- Xv server extension main device independent module.
+**
+** Author:
+**
+** David Carver (Digital Workstation Engineering/Project Athena)
+**
+** Revisions:
+**
+** 04.09.91 Carver
+** - change: stop video always generates an event even when video
+** wasn't active
+**
+** 29.08.91 Carver
+** - change: unrealizing windows no longer preempts video
+**
+** 11.06.91 Carver
+** - changed SetPortControl to SetPortAttribute
+** - changed GetPortControl to GetPortAttribute
+** - changed QueryBestSize
+**
+** 28.05.91 Carver
+** - fixed Put and Get requests to not preempt operations to same drawable
+**
+** 15.05.91 Carver
+** - version 2.0 upgrade
+**
+** 19.03.91 Carver
+** - fixed Put and Get requests to honor grabbed ports.
+** - fixed Video requests to update di structure with new drawable, and
+** client after calling ddx.
+**
+** 24.01.91 Carver
+** - version 1.4 upgrade
+**
+** Notes:
+**
+** Port structures reference client structures in a two different
+** ways: when grabs, or video is active. Each reference is encoded
+** as fake client resources and thus when the client is goes away so
+** does the reference (it is zeroed). No other action is taken, so
+** video doesn't necessarily stop. It probably will as a result of
+** other resources going away, but if a client starts video using
+** none of its own resources, then the video will continue to play
+** after the client disappears.
